So we're better off holding all our XCN instead of selling some of it, because last I checked Bter had less volume and lower prices.

I've got something like 1100MH/s and I'm getting around 16.000 XCN per day from Suprnova (only tried it 36 hours though, been solo mining when it wasn't working) so that amounts to somewhere close to 14.5 XCN per MH/s. So yes, that seems about right.

There has to be something other going on though, because at times, Suprnova has had close to 70-90% of the whole net hash, yet it always has 130%+ luck. Seems like 30% is always disappearing somewhere. I had the exact same issue when solo mining. Pretty much no orphans, close to no rejected yet still about 130% luck. Of course, that was "only" during three weeks, but with close to the same luck every day over three weeks, that does say something.

And again, don't say orphans, because there were pretty much none.
